Issues Encountered installing lirc on new 20.04 device

** The first issue: Missing module and Deprecated syntax

While installing lirc:

If I run at the command line: sudo apt install lirc, it installs
lirc version 0.10.1-6.1ubuntu1.1 successfully.

However, when I run "sudo lirc-setup", I get the following dump;

-------------------------------------------------------------------------

ModuleNotFoundError: No module named '_client'
-------------------------------------------------------------------------

The last line "ModuleNotFoundError: No module named '_client'" is
apparently the same as was found in 18.04 and previously reported.

Note: I only installed from the binary package and did not install any related source package.

The "deprecated calls" also will need addressing, but this is not
required immediately.

** Mis-located Document
   :PROPERTIES:
   :ID: a39c9ba0-7bfe-4ea9-8354-a67519473250
   :END:

See the attached screenshot of the message from lirc-setup when trying
to verify some of the online documentation. The installed document is
not in the location the source code expects, so only the warning message is displayed.

I have completed the install and configuration of lirc manually, but I feel these issues should be resolved to simplify use of lirc by others.
